Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, and in particular to a heat dissipation mechanism of a charging pile. Background Art

[0002] Charging piles are devices used to supply energy to new energy vehicles. With the popularity of new energy vehicles, charging piles have also become common facilities in people's daily lives. Charging piles generate heat in the process of charging new energy vehicles, especially in the fast charging process. Due to excessive heat, the internal temperature of the charging pile is easily too high and malfunctions occur. Therefore, it is necessary to set a heat dissipation device on the charging pile to discharge the heat in the charging pile box in time.

[0003] Existing heat dissipation devices for charging piles usually have air inlets and outlets on the charging pile box, so that air flows between the inlet and outlet to discharge the hot air in the box. Since the inlet and outlet are ordinary through holes, dust in the air will also enter the charging pile box during the heat dissipation process, causing dust or even damage to the internal components, thus affecting the service life of the charging pile. Utility Model Content

[0004] The purpose of the utility model is to solve the above-mentioned problem and provide a charging pile heat dissipation mechanism for dissipating heat from the charging pile while preventing dust in the air from entering the interior of the charging pile.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a charging pile heat dissipation mechanism, comprising at least one air inlet opened at the lower side of the charging pile box and at least one air outlet opened at the upper side of the charging pile box, and an air inlet module installed at the air inlet and an air outlet module installed at the air outlet, the air inlet module is provided with a filter, the air outlet module includes a fan connected to the inner cavity of the charging pile box, a rotating plate is installed on the outside of the fan, the rotating plate has the freedom to rotate in the vertical direction, the rotating plate includes a sealing plate for covering the air outlet channel of the fan and a connecting rod for connecting the rotating shaft, and in a natural state, the rotating plate covers the outside of the fan under the action of its own gravity.

[0006] The above charging pile heat dissipation mechanism filters the air entering the charging pile through the air inlet module through the filter to prevent dust and the like from entering the charging pile box from the air inlet. When not in operation, the rotating plate covers the air outlet to prevent dust and the like from entering the charging pile box through the air outlet, thereby achieving heat dissipation for the charging pile while preventing dust and the like from entering the charging pile box to cause damage to internal components, thereby extending the service life of the charging pile. Arranging a connecting rod on the rotating plate can increase the force arm during rotation, so that when the fan is working, the sealing plate can be blown open with less force.

[0007] As an improvement to the air inlet module, the air inlet module includes a filter installed in the air inlet and a waterproof baffle installed outside the filter. Its function is to filter dust through the filter and prevent rainwater from entering the charging pile box through the waterproof baffle, so as to meet the heat dissipation and waterproof requirements of the charging pile installed outdoors.

[0008] Furthermore, the waterproof baffle includes a bottom plate, a plurality of first vents are formed on the bottom plate at equal intervals, a partition with a bottom opening is provided outside the first vent, and the gap between adjacent partitions forms a second vent, and the position of the second vent is lower than the first vent. Its function is: through the misalignment of the first vent and the second vent, a waterproof platform higher than the second vent is formed on the bottom plate, so as to prevent rainwater from entering the charging pile box from the air inlet.

[0009] As an improvement, the outer contour of the fan is circular, the air outlet module includes a fan fixing seat with a circular outer contour, both ends of the fan fixing seat are stepped holes, the fan is installed at one end of the fan fixing seat, the rotating plate is installed at the other end of the fan fixing seat, and the outer contour of the sealing plate is circular.

Its function is to facilitate the positioning and installation of the fan fixing seat, and at the same time, the rotating plate can enter the interior of the fan fixing seat in a non-working state, making the appearance of the air outlet module more concise and beautiful.

[0011] Furthermore, a first retaining ring is provided on the step at one end of the fan fixing seat, a second retaining ring is provided on the inner side of the sealing plate, the inner diameter of the second retaining ring is larger than the outer diameter of the first retaining ring, and a groove for accommodating the second retaining ring is formed between the first retaining ring and the inner wall of the fan fixing seat. Its function is to further improve the dustproof effect of the sealing plate.

[0012] As another improvement, the outer contour of the fan is square, the air outlet module includes a fan fixing seat with a rectangular outer contour, the middle part of the fan fixing seat is a hollow structure, the fan is installed on the inner side of the fan fixing seat, the rotating plate is installed on the outer side of the fan fixing seat, and the outer contour of the sealing plate is rectangular.

[0013] Furthermore, the fan fixing seat is provided with a plurality of rotating shafts at equal intervals along its height direction, and each rotating shaft is provided with a rotating plate, and adjacent sealing plates have overlapping parts in a natural state. Its function is that the overlapping parts between the sealing plates enable the plurality of rotating plates to seal the air outlet together in a natural state.

[0014] Furthermore, a first stopper is provided below the outer side of the fan fixing seat, and a second stopper is provided above the upper side, and the lower end surface of the lowest sealing plate is lower than the lower surface of the first stopper, and the upper end surface of the highest sealing plate is higher than the upper surface of the second stopper. In a natural state, the inner side surface of the highest sealing plate abuts against the second stopper, and the inner side surface of the lowest sealing plate abuts against the first stopper. Its function is to strengthen the sealing performance of the sealing plate and prevent dust in the air from entering the charging pile box through the gap between the sealing plate and the fan fixing seat.

[0015] Furthermore, there are at least two connecting rods, which are evenly arranged above the sealing plate. The function of the connecting rods is to reduce the weight of the rotating plate while meeting the rotation requirements, so that the rotating plate can be more easily blown open by the fan.

[0016] Combined with the above technical solutions, compared with the prior art, the utility model has the following beneficial effects:

[0017] The utility model provides a charging pile heat dissipation mechanism, which can dissipate heat for the charging pile through the heat dissipation channel formed between the air inlet module and the air outlet module. During the heat dissipation process, the air inlet module can filter the incoming air through the filter to prevent dust and the like from entering the charging pile box. In a non-working state, the rotating plate naturally droops under the action of its own gravity to close the air outlet, preventing dust and the like in the air from entering the charging pile box from the air outlet, thereby preventing dust and the like from damaging the internal components of the charging pile. In addition, the rotating plate is set to a structure composed of a sealing plate and a connecting rod. The sealing plate is used to withstand wind force, and the connecting rod is used to connect the rotating shaft to increase the force arm, so that the rotating plate is easier to be blown open by the fan, ensuring smooth air circulation during the heat dissipation process.

In order to facilitate the discharge of hot air, the air outlet 12 is arranged above the air inlet 11 and close to the top of the charging pile box 1. The air inlet module 2 is provided with a filter 21 for preventing dust in the air from entering the inner cavity of the charging pile box 1 from the air inlet 11; the air outlet module 3a comprises a fan 32a connected to the inner cavity of the charging pile box 1, a rotating plate 34a is installed on the outer side of the fan 32a, and the rotating plate 34a has the freedom to rotate in the vertical direction, and the rotating plate 34a comprises a sealing plate 342a for covering the air outlet channel of the fan 32a and a connecting rod 341a for connecting the rotating shaft.

In the working state, the rotating plate 34a is expanded outward by the wind force of the fan 32a to form an air outlet channel to complete the heat dissipation. In the natural state, the rotating plate 34a naturally droops under the action of its own gravity to close the air outlet channel, thereby preventing dust in the air from entering the inner cavity of the charging pile box 1 through the air outlet 12.

[0028] In order to make the charging pile meet the waterproof requirements when it is set up outdoors, the air inlet module 2 is configured to be composed of a filter screen 21 installed in the air inlet 11 and a waterproof baffle 22 installed on the outside of the filter screen 21, and the waterproof baffle 22 includes a bottom plate 221, and a plurality of first vents 222 are evenly spaced on the bottom plate 221, and a partition 223 with a bottom opening is provided on the outside of the first vent 222, and the gap between adjacent partitions 223 forms a second vent 224, and the position of the second vent 224 is lower than the first vent 222.

[0029] In this embodiment, the outer contour of the fan 32a is circular, the air outlet module 3a includes a fan fixing seat 31a with a circular outer contour, both ends of the fan fixing seat 31a are step holes, the fan 32a is installed at one end of the fan fixing seat 31a, the rotating plate 34a is installed at the other end of the fan fixing seat 31a, and the outer contour of the sealing plate 342a is circular. The fan 32a and the rotating plate 34a are respectively arranged at both ends of the step hole, so that the overall structure of the air outlet module 3a is more compact, and it is also more convenient to install and use as an independent module.

[0030] In order to facilitate the installation and positioning of the air outlet module 3a, a first limit block 311a is provided on the left and right sides of the fan fixing seat 31a, and a second limit block 312a for installing the rotating plate 34a is provided on the upper side.

[0032] Embodiment 2

[0033] Please refer to the attached Figure 4-6 The difference between this embodiment and the first embodiment is that the outer contour of the fan 32b is square, the air outlet module 3b includes a fan fixing seat 31b with a rectangular outer contour, the middle part of the fan fixing seat 31b is a hollow structure, the fan 32b is installed on the inner side of the fan fixing seat 31b, the rotating plate is installed on the outer side of the fan fixing seat 31b, and the outer contour of the sealing plate 342b is rectangular. A plurality of fans 32b with a square outer contour can be installed on the fan fixing seat 31b with a rectangular structure, so as to increase the air volume of the air outlet 12 and improve the air circulation speed in the charging pile box 1 during heat dissipation.

[0034] In this embodiment, there are multiple rotating shafts 33b and rotating plates 34b, and the rotating shafts 33b are installed at equal intervals in the height direction of the fan fixing seat 31b. The connecting rods 341b of the rotating plates 34b are installed on the rotating shaft 33b. There are overlapping parts between adjacent sealing plates 342b in the natural state, so that multiple rotating plates 34b can jointly complete the sealing of the air outlet to prevent dust from entering the inner cavity of the charging pile box 1 through the gaps between the sealing plates. During the heat dissipation process, when the fan 32b is turned on, its wind force blows up multiple sealing plates 342b at the same time, forming multiple evenly arranged air ducts, so that the hot air in the inner cavity of the charging pile box 1 can be evenly discharged to the outside.

[0035] In order to further increase the sealing performance of the sealing plate 342b in the natural state, a first stopper 311b is provided below the outer side of the fan fixing seat 31b, and a second stopper 312b is provided above the upper side, and the lower end surface of the lowest sealing plate 342b is lower than the lower surface of the first stopper 311b, and the upper end surface of the highest sealing plate 342b is higher than the upper surface of the second stopper 312b. In the natural state, the inner side surface of the highest sealing plate 342b abuts against the second stopper 312b, and the inner side surface of the lowest sealing plate 342b abuts against the first stopper 311b, thereby preventing dust in the air from entering the interior of the charging pile box 1 through the gap between the sealing plate 342b and the fan fixing seat 31b. The first stopper 311b and the second stopper 312b can also make the rotating plate 34b open outward at a certain angle in the natural state, so that the upper and lower sealing plates can fit better together under the action of gravity.

[0036] In order to make the rotating plate 34b easier to be blown open by the fan 32b, the connecting rods 341b can be arranged to be evenly arranged above the sealing plate 342b, thereby reducing the weight of the connecting rods 341b while ensuring the connection strength and stability, thereby reducing the resistance of the fan 32b when working.

[0037] The utility model and its implementation methods are described in detail above, and such description is not restrictive. The drawings show only some implementation methods of the utility model, and the actual structure is not limited thereto. Ordinary technicians in this field can be inspired by it and make various modifications, improvements and substitutions without departing from the concept of the utility model, which should all belong to the protection scope of the utility model.
